IMPROVEMENT IN LAMP-BURNERS.

Speciiication 'forming part of Letters Patent No. 121,550, dated December 5, 1871.

To all whom t may concern:

Be it known that I, FAYETTE S. ROBINSON, of Boston, county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Lamp-Burners, of which the following' is a specification:

The nature of my invention consists: First, in arranging the tube and its adjuncts in such a manner that the tube may be swung laterally in the plane of its width, so that the upper end of it, together with the burning part of the Wick, may be adjusted to the orilice of the draughtplate or cone. Second, in several features of construction', which will vbe best understood by reference to the speciiication and drawing.

Figure l is a section of my invention. Fig. 2 is a plan ofthe same. d

The lower part or support B of my burner is stamped up as represented in Fig. 1, and is attached to the principal plate H H H. The central portion H is perforated so as to allow a free circulation of air, and its outer rim is turned up, as shown in Fig. l, and is provided with a sprin g-catch, L, Fig. 2, which, in connection with the lug M, serves to hold the chimney-ring K in position. This chimney-ring K has its outer edge turned up, as shown in Fig. l, and iits closely into the plate H, and has a large central opening, and serves as a support for the draughtplate E, which is connected to it by standards k c.

By having a large central opening in the ring K K, and by holding it in position by its outer edge, I am enabled to support the draught-plate E independently of the Wick-tube, and as the chimney is held by the ring K K and draughtplate E, I am enabled to remove and replace it, together' with the ring K and draught-plate E, without having any part come near to the tube or Wick, and thus become coated with oil and cinders.

The dame-orifice in my draught-plate terminates in depressions o f in the plate, which depressions bring the plate down to its proper position above the tube and near enough to the edges to cause the iiame to spread well. The tube A passes through the lower portion of the *base B, iitting closely, but arranged so the upper part of the tube may swing back and forth in the plane of its Width, the orifice in the plate H being elongated so as to admit of this. The lower end ofthe tube A is so formed that it will iit the orifice in the base B and yet be free to swing. This is effected by forming projections near the lower end to rest upon the inside ofthe base-plate and by bending the lower ends of the sides of the tube outward, thus preventing any longitudinal motion of the tube. The tube A is provided with a link, N, which is pivoted to the clasp 0, O being made fast to the tube. D is a screw Workin g in the end of the link N, and collared at d, when it passes through the base B, so that it cannot move longitudinally; hence, as the screw D is revolved it will cause the link N and the tube A to move. C represents the feed- 'mg device, and is made in the usual manner.

By the use of the movable tube I avoid the too frequent retrimming now found necessary, and can carry a larger flame with more light and less offensive odors, and with less liability of breaking chimneys.

By supporting the draught-plate upon a movable base with open center, as described, and securing it in its place by holders instead of making it part of the burner, it can be instantly removed without disturbing the wick, and thus secure great advantage in cleaning, trimming, and lighting.

The advantage of two separate sets of holders for holding the cone and chimney is, it allows of releasing the cone from its seat and removing the cone and chimney together.

The base-ring K, to which the draught-plate E is attached, is held firmly in position by the lug M and catch L, while the chimney is held by an independent set of fastenings. This set of fastenings may consist of a screw, P, and the projection Q Q, or of a spring-catch, my idea being to hold the chimney by a set of iastenings that are independent of the iastenings for holding the parts of the burner together.

I do not confine myself to any particular mechanical construction of my improved burner, as that may be varied to suit the style of lamp or the manufacturer.

I claim as my invention- 1. The adjustable tube A, in combination with enings Q Q and P, in combination with the plate a lump-burner, arranged substantially ns de- H H provided with fast-enings M and L, subscribed, for the purpose set forth. stautizilly as described, and for the purpose set 2. The combination ofthe screw I), base B, forth. link N, und movable tube A, substantially as FAYETTE S. ROBINSON. described, sind for the purpose set forth. Witnesses:

3. The buse-ring K, standards k la, and WILLIAM EDSON,

draught-plate E F provided with chimney-iast- FRANK G. PARKER. (90)
